PSG team could not use a player like Lionel Messi well. One of the reasons for this is that the coach of the team does not have enough knowledge of how to use a player like Lionel Messi.
So far I have never heard anyone say that to PSG except you today, because if you say the team coach cannot use a player like Lionel Messi, it means that other players cannot be used better by a coach. But when there was still Lionel Messi at PSG I think the coach put him in a very suitable position so that PSG can continue to win trophies in Ligue1 even though PSG have never succeeded in the UCL as long as there was Lionel Messi in the squad in the past.
It would be very ridiculous if someone said about a coach who couldn't provide the best strategy for Messi or couldn't utilize Messi's talent and in fact when Messi was still at Paris SG Christophe Galtier succeeded in achieving the 1st league title for Paris SG and if someone said he failed to utilize Messi to getting the champions league title even now or when Mauricio Pochettino was still the coach of Paris SG also failed to get the champions league title so it would be unfair to just blame the coach because it is difficult to get the champions league title while this club has never had experience in the champions league so anyone can understand this matter.
